Patent DE-4228900-A1 (DE)
Inventor: REICHEL GUNTER
IPC: G01D1/02
Filed: 1992-08-29
Abstract: The invention is used to filter signals out of an interference/useful signal mixture using the signal averaging method. The intention is to solve the technical problem of permitting the use of the signal averaging method even where it has so far been impossible to obtain the synchronisation signal or the period of the regularly occurring interference signal from the signal mixture. The process of the invention can also, of course, be applied if the synchronisation pulse could be found by technical measures. According to the invention, several signal averaging corrections are made in parallel in time with other freely selected intervals. After the repeated linear superimposition of the corrections, the correction signals are standardised and stored, these values or those derived from them are summed over all bases of a correction interval and stored and the period of the repeatedly occurring signal is found therefrom. The process can also be used even with changes in the frequency of the composite signal through a double signal averaging correction device set-up.

Patent DE-4310292-A1 (DE)
Inventor: HEIDEMANN ROLF DR
IPC: H04B10/291
Filed: 1993-03-30
Abstract: In the case of fibre-optic amplifiers, the input light power is monitored in order to switch off the system in which it is contained, or individual system components, for example the fibre-optic amplifier itself, in the event of deficient input light power. In known fibre-optic amplifiers, a part of the input light power is extracted for this purpose through a coupler. However, these couplers produce disadvantages; for example deterioration of the signal-to-noise ratio. In the fibre-optic amplifier according to the invention, a device (4) is used for monitoring the input light power which extracts and evaluates the pumping light not absorbed in the optical waveguide section (2). <IMAGE>

Title: UV radiator for the irradiation of printing inks on objects and method for drying objects provided with printing ink
IPC: F26B3/28
Filed: 1993-06-05
Abstract: The UV (ultraviolet) radiator is provided with a reflector housing which is divided into two parts in a direction parallel to the longitudinal axis of the radiation source. Both parts are fitted so as to be pivotable about an axis which extends parallel to the longitudinal axis of the radiation source, so that in one end position of both parts the reflector housing is open on that side facing the object to be irradiated and in the second end position of both parts the latter form, with their regions facing towards the object, a screen between radiation source and transport web, as a result of which the object is screened with respect to the radiation source. The procedure in this case can be such that in the case of piece by piece transport of the articles or, if appropriate, even a material web, the duration of the effect of the radiation on the object is controlled by means of corresponding actuation of the reflector housing parts.

Patent DE-4325704-A1 (DE)
Title: Circuit for braking vehicles with electric motors
Inventor: STEIN GERALD
IPC: B60L7/04
Filed: 1993-07-30
Abstract: The invention relates to a circuit for braking battery-operated vehicles with two electric motors which are connected in parallel with one another and are connected to a pulse controller, with two field coils which are connected in series with an armature and with two armature diodes (series-wound motors) which are connected in parallel in each case with an armature. One and only one common field diode is now assigned to the two field coils, which field diode is connected in parallel with the two field coils and the two armatures. The invention can also be applied to vehicles with a series-wound motor. Then, one and only one field diode is connected in parallel with the armature and field coil. By means of this wiring, the excitation of the electric motors when braking occurs is increased, as a result of which an uninterrupted (continuous) and more flat current profile across the armatures is produced. There is also the possibility of increasing the clock frequency of the pulse controller. In addition, the generation of noise is reduced.

IPC: E04B9/00
Filed: 1993-09-10
Abstract: A panel (2), in particular a long panel or large cassette (module), can be swung down, with respect to the counter-ceiling which contains it, about a pivot pin (7) which runs as close as possible to the corner and angle region of right-angled flanges (3 and 4), provision being made for a bearing body (6) relative to which the actual panel (2) can be pivoted and which, for its part, is attached on a supporting profile (1) of the counter-ceiling. Consequently, the pivot pin (7) can be laid so close to the base (9) of the panel (2) and in the corner region (8) of the flanges (3 and 4) that, parallel to the pivot pin (7), the panel (2) effects virtually no yielding movement, during the swinging-down operation, into the area adjacent to said panel (2), with the result that an adjacent panel can be connected there with an extremely small spacing or narrow joint. <IMAGE>

Title: Circuit arrangement for monitoring the operating voltage in the ignition system of a motor vehicle
Inventor: KUHLESCH MANFRED
IPC: F02P9/00
Filed: 1993-09-21
Abstract: In ignition systems for internal combustion engines, faults which are superimposed on the battery voltage and which lead to a brief glitch in the supply voltage of the ignition can, under certain conditions, bring about an ignition spark and thus lead to misfiring. The causes of the faults which lead to such misfiring include, for example, a connection terminal which is not seated tightly on the battery of the vehicle or brief opening of the operating switch. A circuit arrangement is described which performs monitoring of the supply voltage and which in the event of an excessively low voltage switches off a current flowing across the ignition coil in such a way that no ignition spark is produced. The switching off takes place by means of a feedback loop which limits the primary voltage of the ignition coil or the collector voltage of the power transistor to correspondingly small values. So that the feedback loop operates even when there is no supply voltage, it draws its feed voltage from the induced primary current of the ignition coil.

Title: Device for activating a hydraulic adjusting element
Inventor: BIENER RAINER
IPC: F15B11/02
Filed: 1993-10-15
Abstract: The invention relates to a device for activating a hydraulic adjusting element with which in particular a lifting mechanism attached to an agricultural machine can be adjusted. A known device of this type has a directional control valve with which the pressure-medium paths to the adjusting element can be controlled and which has a spool which can be acted upon in the one direction by a reference force and in the opposite direction by a control force produced by a control pressure. In addition, the known device includes a first choke, the opening cross-section of which can be adjusted for predetermining the desired value, and a second choke, the opening cross-section of which, by an adjustment of two choke parts relative to one another, can be varied for detecting the actual value. The two chokes are arranged in series one behind the other in a control circuit. The control pressure can be tapped between the two chokes. According to the invention, the second choke has such an opening characteristic that, in the event of an adjustment of the two choke parts relative to one another caused by a disturbance of certain magnitude, the relative change in the opening cross-section is at least largely independent of the initial position of the two choke parts. This ensures that the sensitivity of the system, expressed as a percentage of the entire working range, is at least approximately constant in the entire working range, that is, in a certain system ... an at least ...
